摘要： A nullseamless multiplexer,null as described herein, provides a flexible and efficient system and method for multiplexing embedded coded bitstreams. Further, unlike the conventional JPEG 2000 standard, the seamless multiplexer is capable of decoding multiplexed encoded bitstreams without the need to use a demultiplexing aide as overhead in the encoded signal. In general, the seamless multiplexer provides a novel approach for multiplexing code block bitstreams by using a nulldecoder pointer,null for multiplexing multiple embedded bitstreams without the use of a demultiplexing aide. Consequently, the seamless multiplexer not only reduces any multiplexing overhead, but also allows much smaller granularity of access in reshaping the compressed input signal. In addition, in one embodiment, the seamless multiplexer also uses dependencies between coefficient blocks to further improve overall compression efficiency.
摘要翻译：如本文所描述的，“无缝多路复用器”提供了用于复用嵌入式编码比特流的灵活且有效的系统和方法。此外，与传统的JPEG 2000标准不同，无缝多路复用器能够对多路复用的编码比特流进行解码，而不需要在编码信号中使用解复用技术作为开销。通常，无缝多路复用器提供了一种用于通过使用“解码器指针”复用码块比特流的新颖方法，用于复用多个嵌入的比特流而不使用解复用辅助。因此，无缝多路复用器不仅减少了任何复用开销，而且在重新压缩压缩输入信号时也允许更小的访问粒度。此外，在一个实施例中，无缝多路复用器还使用系数块之间的依赖关系，以进一步提高整体压缩效率。

摘要： Techniques for transmitting voice/data and packet data services such that packet data transmissions have less impact on voice/data transmissions. In one aspect, voice/data and packet data can be multiplexed within a transmission interval such that the available resources are efficiently utilized. In another aspect, the amount of variation in the total transmit power from a base station is controlled to reduce degradation to transmissions from this and other base stations. In a specific method for concurrently transmitting a number of types of data, a first data type (e.g., voice, overhead, and some data) and a second data type are respectively processed in accordance with first and second signal processing schemes to generate first and second payloads, respectively. First and second partitions are then defined in a transmission interval. The first and second payloads are time multiplexed into the first and second partitions, respectively, and the multiplexed payloads are transmitted.

摘要： An image reproduction apparatus that can select arbitrary video/audio data among plural MPEG transport streams which have been recorded in a storage medium at different times, and can re-multiplex the selected video and audio data into one MPEG transport stream to be reproduced. When a MPEG transport stream is recorded in the storage medium, a reference clock is generated from Program_clock_reference in the stream, and then the MPEG transport stream is recorded with the generated reference clock being attached thereto as an Arrived Time Stamp. At the start of reproduction, a common PCR is generated on the basis of the ATS value to be used as a video/audio PCR. Further, as for PTS and DTS, the difference value in the ATS of packets having PTS and DTS in the same video/audio is calculated, and the video or audio is outputted so as not to vary the difference value.

摘要： Described is a communication system including mobile communication devices. In the described system, the mobile devices may be wrist-worn watches such as are in common use today, except that the watches are specially configured to receive data in a nullbroadcastnull mode and transmit and/or receive data in a nulllocalcastnull mode. The localcast mode includes the ability to transmit and receive data in a peer-to-peer fashion, allowing mobile devices to communicate directly with each other. The ability to combine two of these communication modes in a small, integrated and hence inexpensive and low-power package provides many advantages over existing personal communication device solutions.

摘要： In general, a system and method for providing data packet flow control is disclosed. Generally, a switch is provided that contains a series of ports, an arbiter and a hub. The arbiter determines an outgoing port, wherein the outgoing port is one port for the series of ports, for transmission of a data packet received by the switch, determines whether the outgoing port is available to receive the received data packet, and regulates transmission of the received data packet to a destination end node. The hub provides a point-to-point connection between any two of the series of ports and the arbiter.

摘要： A multi-stage bit stream multiplexer that divides multiplexing functions between two or more integrated circuits. The first integrated circuit receives 16 bit streams to produce 4 output bits streams with a nominal data rate of 10 GBPS. A second integrated circuit multiplexes the 4 streams and to a bit stream with a data rate of 40 GBPS. The first IC is made in a standard CMOS process while the second IC is made using processes that support higher switching rates. The first IC produces a source-centered double data rate forward transmit clock from a reference clock selectable from either a crystal oscillator, a voltage controlled oscillator using a loop clock from the receive side of the bit stream multiplexer or a reverse clock generated by the second IC. The reverse clock can be selected as the source of the reference either by default, or in response to a specific condition.

摘要： An 1:n or m:n path protection mechanism is provided. Rather than defining an automatic protection protocol, use is made of the existing tandem connection monitoring function, tandem connection reverse defect indication, and tandem connection trail trace identifier. Upon detection of a failure on the working path segment, the occurrence of this failure is communicated to the far end node by inserting forced RDI into the tandem connection as long as the failure persists. In the case of more than one protected paths, the failed path is identified by means of the unique trail trace identifier received on the protection path. In the case of several protection paths, one network node is defined as slave node which has to follow the switch-over initiated by the master node and choose the same protection path as the master node. Preferably, a combination of two timers enables return from failure condition to normal operation.
摘要翻译：提供1：n或m：n路径保护机制。而不是定义自动保护协议，而是使用现有的串联连接监视功能，串联连接反向缺陷指示和串联连接跟踪跟踪标识符。在检测到工作路径段上的故障时，只要故障仍然存在，就将该故障的发生通过插入强制的RDI传送到远端节点。在多于一个受保护的路径的情况下，通过在保护路径上接收到的唯一路径跟踪标识符来识别故障路径。在多个保护路径的情况下，一个网络节点被定义为从节点，必须遵循由主节点发起的切换，并选择与主节点相同的保护路径。优选地，两个定时器的组合使得能够从故障状态返回到正常操作。
